Is the presence of microvoid coalescence on a metal fracture surface inconsistent with macroscopic evidence of brittle fracture?
Whereas, if the coldworked radius is twenty mm, now what is the radius before being deformed if the ductility percent EL of a coldworked element Cu cylidrical specimen is twenty-five percent?
A square bar with an initial size of 13.2 mm is reduced by cold work to 10.7 mm (still square). If the radius of a cylindrical specimen, same material, was reduced by cold work also to 27 mm, what was its initial radius (mm) if the mechanical properties turns out to be similar to the square bar specimen?

- : During tensile tests, strain hardening was observed for a metal alloy with a tensile strength of 18,000 psi under regular yielding condition. However, when it was pre-stretched to a 0.5% extension (based on the initial length of the specimen), its strength increased to 20,000 psi. If the pre-extension is increased to 5%, what could be the strength of the material?arrow_forwardFrom a microstructure point of view, how do elastic and plastic materials deformations occur?arrow_forward3. Consider a test specimen with the shape of cylindrical rod, 120 mm long to be deformed by tensile load of 28000 N without experiencing plastic deformation or diameter reduction more than 8.5x10-3 mm. Which among the aluminium alloy, brass alloy, steel alloy and titanium alloy are possible candidates with yield strengths 200 MPa, 300 MPa, 400 MPa and 650 MPa, respectively.arrow_forward
